The Headache Myth

Argentina Through Wine · Step 3 of 5 · 2 min read

True allergic reactions are rare. Studies estimate fewer than 1% of people are genuinely sulfite-sensitive — most of them are asthmatics, where sulfites can trigger breathing problems. For asthmatic people, sulfites are a real risk. For most others, they're not.

So what causes “wine headaches”? Several candidates: histamines (more in red wine, especially aged), tyramine (an amino acid in fermented foods), tannins, biogenic amines in low-quality wine, and most importantly — dehydration and alcohol. Each glass of wine triggers diuretic effects; not drinking water alongside is often the real culprit.

There's also evidence of personal sensitivity to specific compounds — some people react to histamines, others to tannins, others to specific yeasts. The “I get headaches from wine” complaint usually has a more specific cause than sulfites.

Understanding Argentine Wine (FAQ)

What makes Argentine Malbec so unique?

Argentina's high-altitude vineyards, particularly in Mendoza's Uco Valley, receive intense sunlight and experience dramatic temperature shifts between day and night. This slows grape ripening, resulting in rich flavors, balanced acidity, and smooth tannins.

How should I plan a wine tour in Mendoza?

We recommend booking tastings at least 2-3 months in advance, especially for prestigious wineries. Focus on one sub-region per day (like Luján de Cuyo or Uco Valley) to minimize travel time and enjoy a relaxed pace.

What are the best food pairings for Torrontés?

Torrontés, Argentina's signature white wine, is highly aromatic with floral notes. It pairs beautifully with spicy Asian cuisine, fresh seafood, and traditional Argentine empanadas (especially those containing corn or cheese).
